“…A hybrid power plant (WG#CRS#2) with higher solar share decreases the biomass consumption by 16 thousand ton per year but, the investment is less attractive because the payback period is higher and the IRR is reduced below the assumed inflation. A forest residues biomass boiler can be integrated in the steam cycle of a CRS with an LCOE of 0.144 €/kWh, IRR of 6.8%, NPV of 7.9 with a payback of 21 years [23]. If waste transport and disposal is necessary, the LCOE of this power plant would increase to 0.16 €/kWh, the IRR and NPV reduce to 4.4% and 0.8, respectively, and the investment will have a payback of 28 years.…”

Central receiver systems (CRS) are a promising concentrated solar power (CSP) technology for dis-patchable electricity generation. The CRS levelized cost of electricity (LCOE) is usually increased by low power-block capacity factors or by high thermal storage costs. The economical turnover is still positive for the Portuguese case but depends on the bonus feedin tariffs. On the other hand, with biomass existing feed-in tariffs and raising prices, the viability of current biomass power plants is at risk. To address these issues, several base case power plants and hybrid biomass/CSP options are analyzed: wood gasification, refusederived fuel pellets, biogas from a wastewater anaerobic digester, biogas from a landfill and natural gas.The solution with lower LCOE was obtained for the hybridization of a 4 MWe CRS using an atmospheric volumetric receiver with biogas from an anaerobic digester using sludge from a wastewater treatment plant (WWTP). Different results would be obtained for the hybrid systems if different CRS technologies are used. The hybrid CRS/anaerobic digester power plant LCOE is 0.15 €/kWh, returning the investment in 13 years (assuming sludge collection and transport without cost) with the best net present value (15 million euro) and internal rate of return of all the hybrid options.

“…Concentrated solar power tower (CSP) plants, for instance, require specific solar irradiation, which are generally not always fulfilled during day time, notwithstanding in the nights. At the current stage, few reports have briefly discussed about hybridisation of solar tower power plants and other conversion technologies using renewable sources, like biomass [4,5]. In the last years, researchers and industry insiders have mainly focused on standalone solar power system with molten salt storage tanks or hybrid power plants with fossil fuelled backup systems for delivering dispatchable power in the absence of sunlight.…”

“…Those authors [7,10] highlighted from the economic side the advantages of hybrid solar power system compared to standalone solar power plants with molten salt storage tanks; even considering the costs of CO 2 avoidance [8,9]. A step towards hybridisation of CSP-biomass had been reported by [4,5]. Coelho et al [4] and Peterseim et al [5] through their capital analysis showed up that such hybridisation (solar-biomass) has the potential to alter the solar market in their favour instead of stand-alone solar power plants and fossil fuelled backup systems.…”

This article begins with a short introduction and continues with a presentation of solar tower power plants around the world. The focus is set on the developments of the last five years and in the near future of the most important components of a central receiver system (CRS). For each of the components, a description of each technology, its applicability, and the advantages and disadvantages is presented. The chapter also includes a state of the art review for almost each system and points out the Research and Development (R&D) needs. A further issue is the choice of the heat-transfer fluid (HTF) as well as the improvement of new solar tower power plant cycle systems. The paper introduces recent R&D activities, with the majority occurring in Europe and the United States, as has been presented in international journals and conferences by scientific personnel. It also reflects opinions of experts who specialized in the planning and erection of solar power plants and carrying out CRS research projects. The future effort of R&D in these fields should improve efficiencies, increase durability and reliability, and reduce investment and Operation & Maintenance (O&M) costs. Nowadays, and in this decade, the most advances in CRS occur in the United States, in Europe, and in China. Furthermore, a great interest, especially for add-ons to existing research platforms as well as the construction of new ones, can be observed for the last years for countries in the Middle East & North Africa region, such as Morocco as well as India, Australia, and South Africa.The challenge for a solar tower cycle is related to ensuring the longevity of the receiver and demonstrating that the receiver material can handle high temperature fluxes across the 25-year lifespan of a plant. A further research step for this technology is to reach even higher temperatures and therefore Receiver Heliostat field HTF Steam HRSG Turbine Thermal storage FIGURE 1 | Scheme of a central receiver system.
